How to glue lego baseplate to table.
I ve seen other tables that they put together lots of smaller base plates to cover the table completely.
Use liquid nails to attach the base plates to the table.
Make sure you put a lot on but do not let it flow out from under the base plate.
But when i found that lego made a 15 15 inch base plate i decided to go that route because it was the easiest.
Finally it s time to attach the baseplates using superglue which will bind them to almost any tabletop.
First cover the back of the base plate with hot glue i used my big glue gun because it is hotter and the glue stays hot longer giving me more time to get it placed in the right spot.
The good thing about this would be you could swap out the plates relatively easily.
Maybe like 2x4 or 2x6 bricks in each of the corners then centered where the plates meet.
You have to work fast on this next part.
Take a lego and attach it to the top of the two base plates so they will be the correct distance from each other.
